Improving Feed Efficiency to Promote a Sustainable Dairy Industry28 December 2016
CANADA - Remarks by Michael VandeHaar, Michigan State University, USA, during the ruminants breakout session at the 2016 World Nutrition Forum in Vancouver, Canada.
Dairy feed efficiency, as defined by the fraction of feed energy and protein captured in products, has more than doubled in many countries over the past 100 years. This increase occurred mostly because of a focus on improving production per cow, but, for the future, we must focus more directly on efficiency. Efficiency can be improved further by using genomic technologies to select for more efficient cattle and by feeding cows to more precisely meet nutrient requirements during different stages of the lactation cycle.
